Thank u , but this method can't draw the text in the edit contol.
SetWindowText()*can* draw the text in the edit-ctrl. In fact, its the only way to do it this side from owner-drawing the whole control. Your way paints the text at the exact place where the Edit-ctrl is located, triggering the edit-ctrls redraw. Your text gets overwritten. If what you want to acomplish is putting your Text into the Edit-ctrl, thenSetWindowText()is the way to tell the Edit-ctrl what text it has to draw. If you want something different, you should subclassCEditand do it yourself, possibly delegating routine tasks to your baseclass CEdit.
